HEEL-ATTACHING MACHINE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed January 28, 1903. Serial No. 140,833.

To aZZ whom it may concern:

Be it known'that I, ERASTUS /VooDwARD, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Heel-Attaching Machines, of which the followingis a specification.

My invention relates to a machine for attaching heels loaded with nailsto the heelseats of boots and shoes, and where blindnailing is employedto the subsequent attachment of top lifts to the attached heels.

My improvement is shown applied to a heeling-machine in which there is avertically-reciprocating cross head carrying a hub adapted to beoscillated about a shaft and, provided with two diametrically-arrangedarms, one of which carries the naildriving mechanism to which the loadedheel is applied for attachment to the shoe and the other arm beingadapted to subsequently attach or spank the top lift onto the attachedheel at the proper time. I have not shown in the drawings the mechanismfor reciprocating this cross-head, as it is too well known in the art torequire description.

My invention consists of certain novel fea tures hereinafter described,and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodyingmy invention, Figure 1 shows a side elevation of the cross-head referredto, together with the jack in position thereunder for holding the shoe,and also showing the loaded heel held on the upper arm, to which it hasbeen applied by the body. Fig. 2 is a similar view with the armsreversed and showing the heel above the jack in position to be attachedto the heel-seat of the boot or shoe. Fig. 3 is a top plan view of Fig..2 and showing the toplift-carrying device out of the vertical line ofmotion of the arm carrying the heel during its attachment to thehcel-seat of the boot or Fig. 4 is a side elevation showing thecross-head down with the heel attached to the shoe. Fig. 5 is a sideelevation similar to Fig. 4 with the arms reversed and showing theprojecting ends of the nails onto which the top lift is to be attached.Fig. 6 is a view similar to Fig. 5 with the cross-head down and thespanker-block attaching the top lift to the projecting ends of thenails.

.Fig. 7 is a view similar to Fig. 6, showing the cross-head raised withthe arms and the heel finished. Fig.8 is a top plan view of thetoplift-earrying device in the position shown in Fig. 1 when the heel isapplied by the boy to the arm carrying the heel-attaching mechanism.Fig. 9 is a top plan detail view of the toplift-carrying device with theparts in the position shown in F 2 out of the driving-line of the armcarrying the heel. Fig. 10 shows a top lift applied to thetop-lift-carrying device and ready to be moved into position under thespanker-block for attachment to the attached heel. Fig. 11 is a top planview of the top-lift-carrying device and in the driving-line of thespanker-alm for attachment of the top lift to the attached heel. Fig. 12is a cross-sectional view through the cross-head on the line a a,Fig. 1. Fig. 13 is a cross-sectional view through the head and hub withthe two arms in full lines on line 1 1, Fig. 2. Figs. 14 and 15 arerespectively side and under side plan views of the mechanism wlichoperates the top-lift-carrying device, representing the parts in theirpositions when the top-liftcarrying device is out in position to receivea top lift. Figs. 16 and 17 represent, respectively, side and under sideplan views of the mechanism which operates the top-lift-carrying device,showing the parts in their positions when the topliftcarrying device ismoved inward with the top lift over the heel for attachment thereto.

Like letters of reference refer to like parts throughout the severalviews.

In the drawings the cross-head A is reciprocated, by means of the rodsA, in the manner well known in the art.

N is the last, carrying the shoe. to which the heel and top lift are tobe attached when blind-nailing is employed and to which the heel only isto be attached when flush-nailing is employed. The hub B, attached fastto the shaft B, which is set at an angle of thirty degrees, carries thediametrically-arranged arms or blocks B B and said hub and arms areadapt ed to be firmly held in position dur ing the attaching operationby the arm 0,

pivoted at C on the cross-head A and nor-.

mally caused to engage a suitable recess in each arm by means of thespring C (Shown in Figs. 1, 2, and 3.) Secured fast to the lower end ofthe shaft B is the arm D,to which is pivotally connected at D the leverD which at its opposite end is pivotally con- -over the attached heelnected to the arm E by the pin D extending down through the opening inthe movable arm E, mounted freely on the sleeve 6 around the rod E,which extends upward from the base of the machine. The end of this arm Eopposite the lever D is supported in the lugs e, secured to andextending from under the cross-head A, and in the movements of the leverD the arm E moves to and fro on the sleeve 6, supported in the lugs 6.From the under side of the arm E there extends downwardly the dependingrod E which passes through the slot E in the bifurcated arm E held faston the rod E by the set-screw E Secured to the boss E on the arm E isthe plate E to which-are pivotally secured two links E E at F and F. Theforward end of the link E is pivotally connected at F to the arm F ofthe link F to which is secured the forward end of the link E at Fforming the well-known parallel motion. The spring F, secured to thelink E at one end and at its opposite end to the pin F tends to hold theforward end of the arm F in a parallel closed position with respect tothe forward end of the plate E and exerts a pressure on thetop lift tohold it square andclamped in a suspended position as it travels intoposi.ion over the attached heel. On the forward end of the plate E aretwo guides G G, inwhich there is adapted to slide the forked plate Ghaving shoulders, as shown, to limit the forward movement of said plateunder tension of the spring G secured to the plate E and to the pin G.

The top lift is placed on the top-lift-carrying device by putting itsbreast against the parallel arm F and forcing said arm out until the toplift Y drops into the fork in the plate G which yields as the arm Freturns to its normal position under the tension of the spring F untilthe back of the top lift strikes the edge of the forward end of theplate E which is the gaging-point of the top lift, the plate Hpreventing the top lift falling through during its application, as abovedescribed. The plate H is located on a-suitable standard extending upfrom the base of the machine and is fixed in positive relation to thearm F and the forward end of the plate E so that when thetop-lift-carrying device is moved out into position to receive a toplift it comes directly over the plate H in close proximity thereto andprevents the top lift when being applied thereto from passing through.

The machine is so organized that when the top lift is arranged asdescribed and brought its rear end comes over the rear end of the heelin a positive relation to the back nail.

Depending from the under side of the lever D is the pin f, to which isattached the spring f, with its opposite end secured to the pin f,depending from the arm E, and located beyond said pin f is the slot Dwhich is longer than the pin D so as to allow a yielding movementbetween the lever D and the arm E. When the top-lift-carrying device isin its outer or receiving position, as shown in Figs. 3 and 4, thecooperating parts shown in Figs. 14 and 15 are in thepositions indicatedin said figures; but when the top lift moves inward over the heel forattachment the cooperating parts shown in Figs. 16 and 17 are in thepositions indicated in those figures.

\Vhen the block B moves downwardly from. the position shown in Fig. 5 tothat shown in Fig. 6, the top lift is spanked onto the attached heel,and owing to the force of. the

blow of the spanker-block B on the rigid heel of the shoe located on thelast the leather of the top lift spreads out, which causes the forwardend of the plate F to move laterally and yield by means of the spring Fand at the same time the forward end of the plate E moves laterally andyields by means of the spring f, so that the top lift is not marred bythe force of the blow of the spanker-block 13*,

its spreading being thus provided for as above described.

The plate E is secured to the boss E carrying the bifurcated arm E, faston the shaft E, and through the slot E of said bifurcated arm E passesthe depending rod E fast to the under side of the arm E. By theconstructions previously described the plate E yields as the rod E movesthe arm E slightly toward the right from the position shown in Fig. 17by the yielding of the spring f, and after the top lift is attached thespring f returns the arm E to the position shown in lhe loaded heels aresecured on the heelblock B by means of the carrying and holding fingersJ, which may be of any desired construction and form no part of thisinven tion. When the boy has placed a loaded heel X on the heel-block Band the same is held there by the fingers J, the boy operates the latchC to release the heel-block and allow it to be turned and brought intothe position shown in Fig. 2; During this operation thetop-lift-carrying device hereinbefore described moves out of alinementunder the spanker-block B in the position shown in Figs. 1 and 8 to theposition shown in Figs. 2 and 9, when the boy places the top lift Y onthe top-lift-carrying device in the manner shown in Fig. 10. In themeantime the operator has placed the shoe A on the jack A and operatesthe cross-head A to bring down the heel from the position shown in Fig.2 to that shown in Fig. 4 for attachment to the shoe and then turningthe arm B brings the heel-block B up into the position shown in Fig. 5.This movement brings the top-liftcarrying device into position over theattached heel and under the spanker-block B Fig. 6, when the operatorbrings the crosshead A down and spanks the top lift onto the attachedheel and upon the rpward movement of the cross-head A leaves the entireheel Y secured to the shoe.

When the parts are in the position shown in Fig. 1, thetop-lift-carrying device is directly under the spanker-block B and overthe shoe; but when the boy throws the block B to bring it around overthe shoe in the position shown in Fig. 2 the top-lift-carrying devicemoves from its horizontal position (shown in Fig. 8) to that shown inFig. 9, ready to receive the top lift by the movement of the lever D armE, rod E and arm E to the boss E, to which the top-lift-carry ing deviceis secured. When the operator turns the arm B to turn the heel-block upand turn the spanker-block down, the toplift-carrying device, which hasreceived a top lift, moves from the position shown in Fig. 10 to thatshown in Fig. 11 through the opera tion of the lever 1)", arm E, rod Eand bifurcated arm E hereinbefore described, when the top lift is inposition to be spanked onto the attached heel. The hub B with the blocksB B do not rotate continuously in one direction, but oscillate in an arcof one hundred and eighty degrees.

Having thus described the nature of my invention and set forth aconstruction embodying the same, what I claim as new, and desire tosecure by Letters Patent of the Uni-ted'States, is
